Learning transformation rules for semantic query optimization: a data-driven approach
Shashi Shekar, Babak Hamidzadeh, A. Kohli, Mark Coyle · IEEE Transactions on Knowledge and Data Engineering · 1993
An approach to learning query-transformation rules based on analyzing the existing data in the database is proposed. A framework and a closure algorithm for learning rules from a given data distribution are described. The correctness, completeness, and complexity of the proposed algorithm are characterized and a detailed example is provided to illustrate the framework.>
